Experimental results for the radio occultation of the Venusian atmosphere using the Venera-9 and Venera-10 satellites are discussed. The time dependences of the field strength and frequency during immersion of the vehicles behind the planet and during their emersion from behind it are given. The dependences of the refraction index, density, pressure, temperature, and electron number density on the altitude above the planet's surface have been obtained. The results of bistatic radiolocation of the Venus surface with the aid of the Venera-10 satellite are also presented. An analysis is made of the energy spectrum and variations of the Doppler frequency of a radio signal reflected from the planet's surface. The distribution of the relative heights and of rms slopes of irregularities for two areas of the Venusian surface has been found.
